the bottom of the cookware). You can also
hold a magnet to the bottom. If it clings to
the underside, the cookware will work on the
induction hob.
To ensure optimum efficiency, always use
pots and pans with a flat bottom that
distributes the heat evenly. If the bottom is
uneven, this will affect power and heat
conduction.
How to use
Minimum diameter of pot / pan base for
the different cooking areas
To ensure that the hob operates properly,
the cookware must have a suitable minimum
diameter as well as cover one or more of the
reference points indicated on the surface of
the hob.
Always use the cooking zone that best
corresponds to the diameter of the bottom
of the cookware.

Empty or thin-based pots / pans
Do not use empty pots / pans or cookware
with thin bases on the hob as it will not be
able to monitor the temperature, or will turn
off automatically if the temperature is too
high. This may result in the damage of the
cookware or the hob surface. If such a
situation occurs, do not touch anything and
wait for all components to cool down.
If an error message appears, refer to
"Troubleshooting".

When a cooking zone is active it may hum
briefly. This is characteristic of all induction
cooking zones and does not impair either
the function or the life of the appliance. The
noise depends on the cookware used. If it
causes considerable disturbance, it might
help to change the cookware.
Normal operating noises of the induction
hob
lnduction technology is based on the
creation of electromagnetic fields to
generate heat directly on the bottom of
cookware. Pots and pans may cause a
variety of noises or vibrations depending on
how they are manufactured. These noises
are described as follows:
• Low humming (like a transformer): this
noise is produced when cooking at a high
heat level. lt is based on the amount of
energy transferred from the cooktop to
the cookware. The noise ceases or quiets
down when the heat level is reduced.
• Quiet whistling: this noise is produced
when the cooking vessel is empty. lt
ceases once liquids or food are placed in
the vessel.
• Crackling: this noise occurs with
cookware comprised of various materials
layered one upon the other. lt is caused
by the vibrations of the surfaces where
different materials meet. The noise occurs
on the cookware and can vary depending
on the amount of food or liquid and the
cooking method (e.g., boiling, simmering,
frying).
• Loud whistling: this noise occurs with
cookware comprised of different
materials layered one upon the other, and
when they are additionally used at
maximum output and also on two
cooking zones. The noise ceases or quiets
down when the heat level is reduced.
• Fan noises: for proper operation of the
electronic system, it is necessary to
regulate the temperature of the cooktop.
For this purpose, the cooktop is equipped
with a cooling fan, which is activated to
reduce and regulate the temperature of
the electronic system. The fan may also
